this is from last year but the manager merry-go-round. Man United sacked their manager, hired Juventus's manager. Who then proceed to hire Pep from Man City, who then get Klopp from Liverpool. Liverpool then get Simeone from Atleti, who then get the guy that Man United fired.
I've also noticed that Set-Piece coaches are consistently moving from club to club. McPhee almost always goes to Liverpool after a week in my saves.
